Title: Improvements relating to the production or refining of aluminium
IPC: C22B21/06
Filed: 1947-06-02
Abstract: A process of producing or purifying aluminium which comprises leaching the aluminium-bearing material with a fused or liquefied halide of aluminium and/or of an alkaline earth metal, or a mixture of such halides with one or more fused halides of the alkali metals in order to dissolve the aluminium from the said material, separating the resulting aluminium containing halide solution from the remainder and recovering aluminium from the solution.  Separation of the solution from the residue may be by filtering, decanting or centrifuging near to or above the temperature of leaching.  Aluminium may be recovered from the solution by cooling and separating precipitated aluminium (a) mechanically by decanting, filtering or centrifuging if the solvent is liquid or by crushing and screening if the solvent is solid; or (b) if the solvent is volatile at relatively low temperatures by distilling it off at normal or reduced pressure, or by a combination of (a) and (b).  The material from which aluminium is to be recovered is preferably brought into a state in which it has a great specific area, before leaching.  Where the vapour pressure of the fused halide solvent exceeds one atmosphere, the process is carried out in pressure-tight vessels.

Title: Improvements in or relating to steering arrangements for vehicles
IPC: B60G3/20
Filed: 1951-06-26
Abstract: 716,320. Steering vehicles. LUDOWICI, J. W. June 26, 1951 [Oct. 1, 1948], No. 15131/51. Class 79(5) [Also in Group XXXII] A steering gear box for a vehicle having at least one pair of steerable wheels or wheel sets arranged symmetrically about the median longitudinal axis of the vehicle, comprises a pair of steering spindles, A, B, each adapted to steer a steering axle of one of the wheels or wheel sets over a steering range of up to 360 degrees, a rotatable guide ring or disc 30, 31, for each steering spindle, the rings or discs being coaxially arranged. means 33, 34, or 36, 37 for transmitting movement of the guide ring or disc to its corresponding steering spindle, a pole disc 24 arranged between the guide rings or discs and adapted to be rotated by a steering wheel 28, the guide rings or discs respectively carrying a pin A1, B1, each engaging in a slot in the pole disc arranged on a diameter thereof. The arrangement conforms to a given geometrical construction such that, if desired, when the vehicle is turning, rolling friction only takes place between the wheels and road surface. In the construction shown, the pole disc 24 is positioned between three rollers such as 25, which engages its periphery and it is rotated by the steering wheel 29 through gearing. Its centre is offset from the centre of the coaxially arranged guide discs 30, 31, and the amount of offsetting is proportional to the height of a perpendicular between a line joining the pivot pins of the wheels connected to the spindles A, B and the locus (parallel to the above line) of the required steering centres of the vehicle to give the above condition of rolling friction only. The distance between the steering spindles A, B is proportional to the distance between the corresponding pivot pins of the wheels. The disc 24 has two slots which are symmetrically arranged on a diameter and one is engaged by pin Al on guide disc 31 and the other by pin B1 on guide disc 30, These guide discs are each connected through 2:1 reduction gear to the corresponding steering spindles A, B and these in turn are connected through reversing mechanism to their corresponding wheel pivot pins. The construction can be modified so that the distance between the centre of the disc 24 and that of the guide discs 30, 31 can be reduced to zero; in a vehicle in which all the wheels are steerable, this allows the wheels to be turned parallel to each other so that the vehicle can move at an angle to its longitudinal axis. In a vehicle having four wheels or wheel sets, all of which are steered, each steering spindle can operate one front wheel or wheel set and one rear wheel or wheel set, one direct and one through reversing gear. In a vehicle with. more than four wheels or wheel sets a plurality of steering gear boxes driven from a common steering wheel may be used. In a modification the guide discs are connected to the steering spindles by slidable members instead of reduction gearing. Arrangements for mounting the wheel sets are also described (see Group XXXII).

Title: Improvements in or relating to automatic control mechanism for aeroplanes
IPC: G05D1/04
Filed: 1938-05-23
Abstract: 515,072. Automatic control systems. SIEMENS APPARATE UND MASCHINEN GES. May 23, 1938. No. 15379. Convention date, May 22, 1937. [Class 38 (iv)] Steering; attitude.- In the automatic control of aeroplane flight in a curve the initiation of a change of course by manual means is accompanied by simultaneous operation of the aileron control device independently of the gyroscope horizon instrument. A switch 1 which determines the direction and speed of movement of the course adjusting motor 3 and the automatic< >pilot transmits also to windings 31 of an electromagnetic device 16 controlling the aileron a current fixed in value but directed according to the direction of course adjustment. The gyroscopic horizon instrument 5 comprising a bolometer diaphragm 12 produces in windings 15 a current multiplying the effect of winding 31 when a predetermined banking angle, e.g., 5 degrees, is reached. Banking is then controlled by an instrument responsive to transverse acceleration such as a sector shaped pendulum 25 strongly restrained by springs 23, 24 and geared at 26 to a bolometer diaphragm 27 associated with windings 30 on the servomoter. Other means for producing the inital operation of the device 16 may be employed such as a resistance inserted in one or other of the arms of the bridge circuit including the elements 12, 13, 14 and 15. The horizon instrument 5 comprises a supervisory controlling pendulum 17 and coil 21 and during course changing the influence of this is removed at the same time as the effect of the pendulum 25 is established by a relay 35 energized from the course changing switch 1. The device 16 may be controlled otherwise according to the selection between the apparent and true vertical. Fig. 2 indicates at 37 an instrument in which electrical quantities representative of the speed of flight and the speed of rotation of the craft on a vertical axis are multiplied to cause deflection of a member 39 in accordance with the apparent vertical. whilst a member 42 is maintained in the true vertical by correction to the diaphragm 12 operated by the horizon instrument. These two members constitute a switch energizing the windings 30. The conductors 50 may be energized in accordance with the excitation of the motor 3 and the conductors 38 by means of an air log.
